SMOKE-BELL SUPPORT.

T 0 all whom it may concern:

Be it known that I, DANIEL F. MCCARTHY, a citizen of the United Statesof America, residing at McKeesport, in the county of Allegheny and Stateof Pennsylvania, have invented certain new and useful Improvement inSmoke-Bell Supports, of which the following is a specification,reference being had therein to the accompanying drawing.

This invention relates to smoke bell supports for use in connection withgas fixtures and the object thereof is to provide a support of suchclass in the manner as hereinafter set forth and claimed and which shallbe simple in its construction and arrangement, durable, efficient in itsuse, strong, readily set up in operative position with respect to thefixture enabling the convenient positioning of the smoke bell andinexpensive to manufacture.

\Vith the foregoing and other objects in view the invention consists ofthe novel construction, combination and arrangement of parts ashereinafter more specifically described and illustrated in theaccompanying drawings, wherein is shown the preferred embodiment of theinvention, but it is to be understood that changes, variations andmodifications can be resorted to, which come within the scope of theclaim hereunto appended.

In the drawings wherein like reference characters denote correspondingparts throughout the several views, Figure 1 is an elevation of aninverted lamp showing the adaptation therewith of a smoke bell supportin accordance with this invention, Fig. 2 is a sectional elevation of anordinary gas fixture showing the adaptation therewith of a smoke bellsupport in accordance with this invention, and Fig. 3 is an invertedperspective view of the base of the smoke bell support.

Referring to the drawings by reference characters, 1 denotes a gasfixture provided with a cut-off 1 and further provided with an elbow 1which is formed with a vertically-disposed screw threaded nipple 1 ofless diameter than the diameter of the elbow 1 whereby a shoulder 1 isprovided at the junction of the nipple 1 with the elbow 1*. Attached tothe nipple 1 is a Bunsen burner 2 which has connected thereto aninverted lamp 3.

Referring to Fig. 2, 2* denotes a gas fixture provided with an elbow 2having pro- Specification of Letters Patent.

Serial No. 526,061.

jecting therefrom a vertically-extending screw-threaded nipple 2 of lessdiameter than the elbow whereby a shoulder 2 will be formed at thejunction of the nipple 2 with the elbow 2*. To the nipple 2 is attacheda burner 3 The foregoing elements referred to in connection with Figs. 1and 2 are of known construct-ion.

A smoke bell support in accordance with this invention and as shown inFigs. 1 and 2 includes a base plate a which gradually decreases in widthfrom one end toward the other and at its enlarged end is formed with anopening 5 surrounded by a cut-away or beveled or counter-sunk portion 6to provide a seat whereby the plate can be mounted upon one end of anelbow, the said end abutting against the seat. The base plate 4 at itssmaller end is formed with a screwthreaded opening 8.

The smoke bell support further comprises a suspension arm and in Fig. 1the said arm consists of a vertically-extending portion'lO and aright-angularly disposed portion 11, which projects from the upperterminus of the portion 10. The portion 10 at its lower end is threaded,as at 9 and the said threaded portion is adapted to engage in thethreaded opening 8 whereby the suspension arm is adj ustably connectedto the base plate 4 so that the said suspension arm can be elevated andlowered when occasion so requires. The right-angularly disposed portionof the suspension arm is provided with a notch 11 in which is adapted tobe mounted the hanger 12 carried by the smoke bell 13.

The suspension arm as shown in Fig. 2 consists of a vertically-extendingportion 1O provided with screw-threads engaging in the threaded opening8 of the base plate. The portion 10 terminates in an angularlydisposedportion 10 the latter merging in a vertically-extending portion 10 whichterminates in an angularly-disposed portion,

10 which is formed with a notch 11 for the reception of the hanger 12 towhich is connected the smoke bell 13. The suspension arm as shown inFig. 3 is vertically-adjustable owing to the providing of the portion l0with screw-threads. The smoke bell 13 can be shifted upon theangularly-disposed portion 10 When the smoke bell support is arranged inposition, the base plate 4 thereof is mount ed upon the elbow 1 or theelbow 2 the cut-away portion 6 of the base plate providing a clearancewhereby the upper por tion of the elbow can extend into the plate 4, thenipple 1 or the nipple 2 extending through the opening 5. The base plate4 is clamped in position by the burner 2 or 3 the burner being screweddown upon the nipple and fixedly securing the base plate in positionupon the elbow.

The right-angularly disposed portion 10 of the suspension arm shown inFig. 2 is provided so that the smoke bell 13 will be supported directlyabove the jet.

The cutaway portion 6 in the plate 4 provides for the threaded nipple tobe engaged for a sufiicient portion of its length by the burner toprevent leakage as is obvious.

What I claim is:

A smoke bell support comprising a base plate adapted to be mounted uponthe elbow of a gas fixture and formed with a cut-away portion to providean interiorly-arranged seat against which abuts the elbow, said platefurther provided with an opening communicating with said cut-awayportion through which is adapted to extend a threaded nipple carried bythe elbow, and a suspension arm connected to said base plate and adaptedto suspend a smoke bell.

In testimony whereof I afl ix my signature in the presence of twowitnesses.
